# List of siege artillery

Siege artillery (also siege guns or siege cannons) are heavy guns designed to bombard fortifications, cities, and other fixed targets. They are distinct from field artillery and are a class of siege weapon capable of firing heavy cannonballs or shells that required enormous transport and logistical support to operate. They lacked mobility and thus were rarely useful in more mobile warfare situations, generally having been superseded by heavy howitzers (towed and self-propelled artillery), strategic bomber aircraft, surface-to-surface missiles, ballistic missiles, cruise missiles and multiple rocket launchers in modern warfare.
